LAMP SOCKET.

Original application filed August 18, 1924, Serial No. 732,706. Divided and this application filed April 30,

1925. Serial No. 26,969.

- The invention relates to lamp sockets and is a division of the application filedAugust 18, 1924, Serial Number 732,706.

In accordance with the principal object of the. present invention, the lamp socket is so constructed that it has self contained means for adjustment whereby the socket may be adjusted throughout a wide range.

A further object consists in sectionalizing the cover of the socket whereby the body of the socket maybe brought out of alignment with the terminal cover portion and the body and lamp adjusted in accordance with requirement.

To the accomplishment of the objects stated and others that will become apparent upon perusal of the description of the invention, the latter comprises a means set forth in the specification, particularly pointed out in the claim forming a part thereof, and illustrated in the accompanying drawing, in which,

Figure 1, is an elevational view of the socket as applied to a wall bracket, the ad justed body shown in dotted lines,

Figure 2, is a front view of the cover: of the lamp socket,

Figure 3 shows the sections of the cover separated and part of the cover in section,

Figure 4: is a perspective view of the lower part of the cover,

Figure 5 is a perspective view in section of the assembled cover.

Referring to the several views of the drawings, 10 generally designates a wall bracket to which a socket generally designated by 11 may be secured by means of a set screw 12. The socket comprises a body portion or shell 13 whilethe cover comprises a sectionallzed body 11,which includes upper portion 15 and a lower part 16, which are separate parts and ar'edivifded along a plane forming an angle of 45 with respect to the horizontal plane. It is, of course, not necessary that the line of division should form an angle of 45 to the horizontal plane, but any other angle may be preferred or resorted to in accordance with special requirements which are to be met.

The upper part 15 has a collar 17 and a hollow portion 18 terminating in a slanting plane 19 from which projects a ring 20. The lower portion 16 includes a circular flange 21'from which upstands a hollow body 22 terminating in a slanting face 23, parallel to the slanting face 19 of the upper member 15 and equipped with an aperture 24 for the insertion of the ring 20.

The slanting faces of the parts 15 and 16 are in contact one with the other, and constitute an oblique joint, whereby, when the part 16 is turned relatively to the part 15, said part 16 will have an orbital movement while turning on its axis. This orbital movement will, because of the close relationship of the parts 15 and 16, be restricted, and may therefore take place without contact of the bulb of the lamp with an adjacent object, such as a lamp shade. The sectionalized body 14 is substantially a sphere which has a minimun linear dimension that affords a short radius, whereby the orbital movement is further restricted.

In order to secure the parts 15 and 16 of the cover together, the ring 20 is inserted through the aperture 24 and is then headed over as shown in Figure 5, whereby the upper part 15 of the cover is rotatably secured to the lower part 16. Attention called, to the fact that if an adjustment is efiected between. the two parts of the cover, there is a relative movement between the two parts which is simultaneously a rotary and vertical movement so that the lower part of the cover, for instance, upon rotation may be brought out of the alignment position shown in Figures 1 or 5 toa position at right angles thereto, as shown in Figure 1 in dotted lines. I It is very desirable to permit the adjustment of the lower part of the cover and therewith of the shell ,13 attached thereto, especially when the lamp carried by the socket is to be removed.

While the drawing discloses a preferred embodiment. of the invention, numerous changes and alterations may be made within the purview of the invention without departing therefrom. I, therefore, do not limit myself to the details of constructionand arrangement as shown, but include all changes constituting of said parts having an aperture, and the departures Within the scope of the invention, Wall of the other of said parts having a 10 as set forth in the appended claim. headed tubular projection extending through I claim: said aperture to hold the parts together but An electric lamp socket of the standard permitting rotary movement thereof. type including, a body portion, and a cover In Witness whereof I'afli'x my signature. therefor, the latter being made in parts and divided in an oblique plane, the Wall of one JACOB RIBAYSEN.
